Description
Rename the specified pin on a hierarchical cell in the current synthesized or implemented design.
- Pins on primitive cells cannot be renamed.
- A pin on a hierarchical cell that has the DONT_TOUCH property can be renamed, but a pin on an hierarchical cell inside a DON'T_TOUCH cell cannot be renamed.
- You cannot rename individual bits of a bus pin, but you can collectively rename the whole bus.
write_checkpoint
command, or may be exported to a netlist file such as Verilog, VHDL, or EDIF, using the appropriate write_*
command.
Changes to the names of cells, nets, pins, and ports, will also affect the design constraints defined in the in-memory design. Constraints are automatically modified to target the new object name, however these are not written back to the source XDC file. Saving the modified in-memory design using write_checkpoint
will save both the renamed objects and modified constraints.
This command returns nothing if successful, or an error if it fails.
Arguments
-to
<arg> - (Required) The new name to assign to the specified pin. The new name only needs to specify the pin name, rather than the whole hierarchical name of the pin. Specified names can not contain Tcl special characters: '"\{};$#
-quiet
- (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
-verbose
- (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config
command.<pin> - (Required) The hierarchical name of a pin, starting with the instance name of the cell it is found on.
Examples
rename_pin -to in1 egressLoop[0].egressFifo/I1
rename_pin -to din[0] egressLoop[0].egressFifo/buffer_fifo/dataInput[0]
WARNING: [Coretcl 2-1480] rename_pin can not rename bits of a bus, \
use resize_pin_bus instead.
